The digital image processing apparatus 100 may also include a flash memory 40 that stores algorithms and setting data for operating the digital image processing apparatus 100, and a secure digital (SD)/compact flash (CF)/smart media (SM) memory card 50 which is a recording device for storing image files.

In addition, a liquid crystal display (LCD) 60 is mounted in the digital image processing apparatus 100. Also, the digital image processing apparatus 100 may include an audio signal processor 71 that converts audio signals to digital signals, converts the obtained digital signals to analog signals, and generates audio files, a speaker 72 that outputs audio signals, and a microphone 73 that inputs audio signals. In addition, the digital image processing apparatus 100 includes a digital signal processor 80 that controls operations of the digital image processing apparatus 100.

The above components of the digital image processing apparatus 100 will be described in more detail as follows.

The optical unit 11 may include a lens unit that collects optical signals, a diaphragm that adjusts an amount of the optical signal that passes therethrough (light intensity), and a shutter that controls an input of the optical signal through the optical unit 11. The lens unit may include a zoom lens that narrows or widens a viewing angle according to a focal length and a focus lens that focuses light of an optical signal from a subject onto the imaging device 12. The lens unit may include one lens or a plurality of lenses. The shutter may be a mechanical shutter, a barrier of which moves in a vertical direction. Otherwise, instead of using the shutter, transmission of electric signals to the imaging device 12 may be controlled to perform a function of the shutter.

The motor 14 that drives the optical unit 11 may control a location of the lens, opening/closing of the diaphragm, and operation of the shutter in order to perform operations such as auto-focusing, automatic exposure adjustment, diaphragm adjustment, zooming, and focus change.

The motor 14 is controlled by the driver 15. The driver 15 controls the operation of the motor 14 according to a control signal input from the digital signal processor 80.

The imaging device 12 receives optical signals input from the optical unit 11 to create an image of a subject. The imaging device 12 may be a complementary metal oxide semiconductor (CMOS) sensor array or a charge coupled device (CCD) sensor array.

The input signal processor 13 may include an analog/digital (A/D) converter which converts the electric signals provided from the imaging device 12, that is, analog signals, into digital signals. In addition, the input signal processor 13 may include a circuit which performs signal processing such as gain adjustment or waveform normalization with respect to the electric signals provided from the imaging device 12.

The user interface (UI) 20 may include an element for performing various settings when the user operates the digital image processing apparatus 100 or photographs. For example, the element may be a button, a key, a touch panel, a touch screen, or a dial. User control signals for turning power on/off, start/stop photographing, start/stop reproducing, searching for images, operation of an optical system, mode conversion, menu control, and selection control may be input by manipulating the element.

The SDRAM 30 temporarily stores RAW image data (RGB data) provided from the input signal processor 13. A predetermined operation with respect to the RAW image data temporarily stored in the SDRAM 30 may be performed according to an operation of the digital signal processor 80, or the RAW image data may be transferred to other components. In addition, the SDRAM 30 may temporarily store executable data corresponding to an algorithm stored in the flash memory 40 after converting data included in the algorithm to executable data. The digital signal processor 80 performs a calculation process using the data temporarily stored in the SDRAM 30 to execute operations according to the algorithm stored in the flash memory 40. In addition, image data which is converted from image files by extracting the image files stored in the flash memory 40 may be temporarily stored in the SDRAM 30. The temporarily stored image data may be transferred to and displayed on the LCD 60.

The flash memory 40 may store an operating system for operating the digital image processing apparatus 100, an application program, and data for executing the algorithm for controlling the digital image processing apparatus 100. The flash memory 40 is just an example, and accordingly, various non-volatile memory devices such as a read only memory (ROM) may be used.

The SD/CF/SM card 50 may record image files generated by compressing image data provided from the input signal processor 13.

The LCD 60 may display images corresponding to the image data provided from the input signal processor 13 in real time, or may display images corresponding to the image data restored from the image files stored in the SD/CF/SM card 50. Although the LCD 60 is described in the present embodiment, an organic electroluminescence device or an electrophoresis display device may be used as the display unit.

The audio signal processor 71 converts audio digital signals provided from the digital signal processor 80 into analog signals, amplifies the analog signals, and transfers the amplified analog signals to the speaker 72 that outputs the amplified analog signals. Otherwise, analog signals are input through the microphone 73, and the input analog signals are converted into digital signals and compressed into audio files. In addition, the compressed audio files may be transferred to the digital signal processor 80 to perform calculation processes with respect to the audio files.

The digital signal processor 80 may reduce noise of the input image data, and may perform image signal processing such as gamma correction, color filter array interpolation, color matrix, color correction, and color enhancement. In addition, the image data generated by processing image signals may be compressed into image files, or the image data may be recovered from the image files. The compression type of the image files may be reversible or nonreversible. As an example, the image data may be compressed in joint photographic experts group (JPEG) files or JPEG2000 files.

In addition, the digital signal processor 80 may perform processes such as processing of non-clear image, coloring, blurring, edge emphasizing, image analyzing, image recognition, or effecting of images. The image recognition may be a scene recognition process. In addition, the digital signal processor 80 may process display images that will be displayed on the LCD 60. For example, the digital signal processor 80 may perform brightness level adjustment, color adjustment, contrast adjustment, contouring adjustment, screen division, character image generation, and image combination.

The digital signal processor 80 may be connected to an external monitor 200 and may perform a predetermined image process to display images on the external monitor 200. In addition, the digital signal processor 80 may transfer image data to the external monitor 200 so that the corresponding images may be displayed on the external monitor 200.

The digital signal processor 80 performs the image processing as described above, and controls each of the components in the digital image processing apparatus according to results of the image processing. In addition, the digital signal processor 80 may control each of the components in the digital image processing apparatus according to a control signal input by the user via the UI 20. The algorithm for performing the image signal processing is stored in the flash memory 40, and the algorithm is converted to executable data in order to perform the calculation process and the executable data is stored in the SDRAM 30. Accordingly, the digital signal processor 80 may perform the corresponding calculation process. In addition, the digital signal processor 80 makes the recognized scene displayed on the LCD 60 during the Scene Recognizing Mode. Configurations for reproducing moving picture files successively by the digital signal processor 80 are shown in FIG. 3.

FIG. 2 is a pictorial diagram illustrating processes of reproducing moving pictures according to the conventional art.

According to the conventional art, when a moving picture file from among a plurality of moving picture files is reproduced, the moving picture file is reproduced only once from a first frame to a last frame thereof, and then, the reproducing process is automatically terminated. According to the conventional art, the moving picture files cannot be reproduced successively. Accordingly, when all of the moving picture files are to be reproduced, as many operations as the number of moving picture files have to be performed.

FIG. 3 is a block diagram of an internal structure of a digital signal processor (DSP) 300 of the digital image processing apparatus 100, which classifies moving picture files and successively reproduces the moving picture files, according to an embodiment of the present invention. The DSP 300 may include an embodiment of the DSP 80 of FIG. 1.

Moving picture files may be successively reproduced using two methods as presented in the following exemplary embodiments of the present invention. However, the present invention is not limited to these embodiments.

In an example of reproducing the moving picture files successively, a moving picture detector 310 detects moving picture files from among various files, and the detected moving picture files are reproduced successively. FIG. 4 is a flowchart illustrating a process of automatically reproducing all the moving picture files stored in the digital image processing apparatus 100 successively, according to the present embodiment.

In another example of reproducing the moving picture files successively, a moving picture detector 310 detects the moving picture files from among various files, classifies the detected moving picture files according to a user's selection, and the classified moving picture files are reproduced successively. FIGS. 5 and 6 are flowcharts illustrating processes of classifying the moving picture files and reproducing the moving picture files. These two examples will be described in more detail as follows.

Referring to FIG. 3, a digital signal processor (DSP) 300 includes a moving picture detector 310, a frame classifier 320, a list storage unit 330, and a successive reproducing unit 340.

The digital signal processor 80 or 300 stores various types of files received from the UI 20, the input signal processor 13, the SDRAM 30, the flash memory 40, and the SD/CF/SM card 50. For example, the digital signal processor 80 may process various files, for example, image files such as JPEG files and BMP files, audio files such as MP3 files and way files, and moving picture files such as MP4 or AVI files.

The moving picture detector 310 detects the moving picture files from the files stored in the storage unit of the digital signal processor 80, based on the file extensions of the files. The moving picture detector 310 may refer to a design rule for camera file systems (DCF) list to detect moving picture files by selecting the files having a file extension such as avi from among various kinds of files having file extensions such as jpeg, way, avi, etc.

The frame classifier 320 classifies one or more moving picture files detected by the moving picture detector 310 based on index frames of the moving picture files. The index frame may be a top image or a representative frame image of the moving picture file. The frame classifier 320 may classify the moving picture files according to criteria such as recorded time, face recognition, detected faces, color information, and recorded sound.

For example, when the plurality of moving picture files are classified based on the recorded time, it may be recognized that the moving picture files are taken during daytime or nighttime by using time data indicating the time when the file has been generated in the index frame.

If the user wants to watch moving picture files including persons or moving picture files including various scenes, the frame classifier 320 may classify the moving picture files according to the face recognition criteria. For example, when the face recognition criteria is selected, the frame classifier 320 may classify the moving picture files into moving picture files including persons and moving picture files including scenes based on the index frame by using a FACE DETECT algorithm.

Otherwise, the frame classifier 320 may classify the moving picture files including scenes by using color information so that the classified moving picture files may be reproduced successively. For example, when the moving picture file has an index frame, in which a scene including a certain color, for example, the scene of sea or sky is included, the moving picture file may be classified as a moving picture file including a scene.

As another example, the user may classify the moving picture files based on recorded sound. The index frames are classified according to the recorded sound, and accordingly, the moving picture files including the index frames may be recognized as to whether the moving picture files include scenes such as concert scenes or not.

The list storage unit 330 stores a list including the moving picture files classified by the frame classifier 320, and accordingly, when the user wants to reproduce moving picture files of a certain classification successively, for example, moving pictures including persons or moving pictures including scenes, the user may choose the list including the corresponding moving picture files.

The successive reproducing unit 340 may successively reproduce the moving picture files according to the list stored in the list storage unit 330 or may successively reproduce all of the moving picture files detected by the moving picture detector 310 when the user wants to watch all moving picture files.

FIG. 4 is a flowchart illustrating a process of automatically reproducing all of the moving picture files stored in the digital image processing apparatus 100 successively, according to an embodiment of the present invention.

After reproducing the moving picture file by the digital signal processor 80 (S410 and S420), it is determined whether the next file is a moving picture file or not in the DCF list (S430). When the next file is a moving picture file, the corresponding moving picture file is successively reproduced (S431), and when the next file is not a moving picture file, the next file is searched for in the DCF list (S432). In addition, the operation of determining whether the next file is a moving picture file is performed again (S430). The above operations are repeated until the end of the DCF list so as to search for the moving picture files and successively reproduce the moving picture files.

FIG. 5 is a flowchart illustrating a process of successively reproducing the moving picture files that are classified according to a classification criterion from among the moving picture files stored in the digital image processing apparatus 100, according to an embodiment of the present invention.

In the present embodiment, the moving picture files are classified by using index frames of the moving picture files. The index frame may be a top image or a representative frame of the moving picture file (S510).

The index frames of the moving picture files may be classified according to criteria such as recorded time, face recognition, detected faces, color information, and recorded sound information (S520). Detailed examples of the criteria are described with reference to FIG. 3.

The list including the moving picture files that are classified according to the criterion may be stored as a linked list (S530). When the list is stored in the form of a linked list, the user may easily reproduce the moving picture files later.

FIG. 6 is a flowchart illustrating processes of classifying the moving picture files and successively reproducing the moving picture files in the digital image processing apparatus 100, according to an embodiment of the present invention.

The digital signal processor 80 detects the moving picture files from among image files, audio files, and moving picture files stored in the storage unit in order to successively reproduce the moving picture files in the digital image processing apparatus. That is, when one moving picture file is reproduced and the reproducing is terminated, it is determined whether a next file is a moving picture file or not in the DCF list (S610-S630). The moving picture file may be detected by using file extensions. However, the method of detecting the moving picture files may be variously modified.

When the next file is not a moving picture file in the DCF list, the operation of searching for a moving picture file is repeated until a moving picture file is detected in order to classify the moving picture files (S630 and S632).

After detecting the moving picture files, the index frames of the moving picture files are uploaded (S640) to classify the moving picture files according to various criteria (S650). The criteria for classifying the moving picture files may include recorded time, face recognition, number of detected faces, color information, and recorded sound information of the index frames in the moving picture files. The criteria are described above with reference to FIG. 3. After that, the reproducing list of the moving picture files is stored as a linked list (S660). Then, when a user selects the successive reproducing of moving picture files (S670), operations of S610 to S660 may be repeated.

FIG. 7 is a pictorial diagram showing an example of a menu for successively reproducing the moving picture files in the digital image processing apparatus 100, according to an embodiment of the present invention.

Referring to FIG. 7, a hot key or a menu may be provided in the digital image processing apparatus so that the user may select successive reproducing of the moving picture files. When the user selects Yes with regard to successive reproducing of the moving picture files (operation S710), the criteria may be provided to the user (operation S720). When the moving picture files are reproduced according to the criterion selected by the user, the corresponding moving picture files may be successively reproduced through the operations illustrated in FIG. 6.

According to the present invention, moving picture files may be successively reproduced in a digital image processing apparatus which can play moving picture files. Therefore, a user may successively reproduce moving picture files without having to separately display each of the moving picture files.

In addition, according to the present invention, moving picture files which are similar to each other may be classified, and then, the classified moving picture files may be reproduced successively.

In general, an apparatus for performing the methods of classifying moving picture files and/or successively reproducing moving picture files according to the embodiments of the present invention may be implemented using any general purpose computing device or devices. Any of the computing devices may comprise a processor, a memory for storing program data and executing the program data, a permanent storage such as a disk drive, a communications port for handling communications with external devices, and user interface devices, including a display, keyboard, mouse, etc. When software modules are involved, these software modules may be stored as program instructions executable on the processor on a computer-readable storage medium, where the program instructions stored on this medium can be read by the computing device, stored in the memory, and executed by the processor.
